AI Automation for AutoCAD
Describe the drawing change. PrismCAD does the CAD work.
Use plain English to automate repetitive AutoCAD operations. PrismCAD turns your request into a structured command plan, shows you what it intends to do, and waits for your approval before execution.
You review every operation before it runs. Your DWG stays local.

PrismCAD is an AI-assisted AutoCAD plugin that converts natural-language drawing requests into constrained, reviewable AutoCAD operations. Users review and approve the generated operation plan before execution.

Tell AutoCAD what you want changed.
PrismCAD converts supported natural-language requests into exact AutoCAD operations you can inspect before execution. The walkthrough below is the live product panel, not a mockup.
Prompt → plan → review → result
Watch the plugin inside AutoCAD. The first seconds show the CAD workspace, a natural-language request, and the operations PrismCAD intends to run.
Supported now
What can PrismCAD do?
These are operations in the current catalog. PrismCAD will not invent an AutoCAD command that is not on this list.
Work with drawing data
- Update supported block attributes
- Work with the current selection
- Apply changes to named blocks or layers
set material code WC-02 for all toilets
Architectural automation
- Add a toilet
- Insert a door at the cursor
- Place a wall
- Add a window
insert a door at the cursor
Spaces and labels
- Label a selected space
- Record room name and floor
- Extract existing room tags

Three real workflows
From a sentence to an AutoCAD operation plan
Each example uses a request the current plugin can plan. Demo A is taken from the captured beta panel on Floor Plan Sample.dwg.
Demo A — Modify existing geometry
Rotate and move a large selection
Promptrotate the selection 85 and move south 76
Plan shown for review
RotateEntities
angle: 85°
MoveEntities
direction: south · distance: 76
After approvalAutoCAD executes the approved operations. The panel records a successful execution ID.
This is the actual prompt and plan visible in the product screenshot. Direction and distance use the drawing’s current units.
Demo B — Architectural workflow
Insert a supported fixture
Promptinsert a door at the cursor
Plan shown for review
Insert supported fixture
door at the current drawing cursor
After approvalPrismCAD inserts the door at the cursor. The same catalog supports add a toilet, place a wall, and add a window.
PrismCAD does not yet create a complete 12′ × 14′ office from one prompt. It inserts the supported element you asked for.
Demo C — Repetitive CAD task
Update block attributes across the drawing
Promptset material code WC-02 for all toilets
Plan shown for review
Update block attributes
value: WC-02 · target: all toilets
After approvalMatching toilet blocks receive the new material code. Selection-scoped updates such as set material code to WC-01 on selection also work.
The target blocks must contain the requested attribute tag, such as MATERIAL or MAT_CODE.
Why this saves timeInstead of opening each block and editing the same attribute, you describe the change once, inspect the plan, and approve it.
Time
Stop repeating the same CAD commands all day.
PrismCAD replaces a click-through command sequence with a sentence you can inspect. No published timing study is claimed here.

Why PrismCAD
Built for people who already know AutoCAD
Faster repetitive work
Describe the result instead of clicking through the same move, rotate, copy, or attribute sequence.
Review before execution
See the named operations and parameters before anything runs. Cancel leaves the drawing unchanged.
Local drawing context
DWG and DXF bytes stay on your computer. PrismCAD is not a cloud CAD file store.
Deterministic operations
Natural language resolves into a constrained AutoCAD operation catalog, not unrestricted generated code.
Control
AI shouldn't have unchecked access to your drawing.
PrismCAD does not let a language model emit arbitrary AutoCAD commands against a production DWG. Supported intent becomes constrained operations. Those operations are validated, shown to you, and executed only after approval.

Workflows
Real AutoCAD problems PrismCAD can take
Each linked page is a supported workflow, not a keyword paragraph. Use them as first-run recipes after activation.
Move objects with plain English
Select furniture, fixtures, or walls and describe the move and rotation instead of repeating MOVE and ROTATE.
Update block attributes
Change MATERIAL or MAT_CODE on a selection or on all matching blocks, such as toilets.
Insert doors, walls, and fixtures
Add a supported toilet, door, wall, or window, then review the insertion plan before it runs.
For CAD managers and IT
Built for controlled CAD automation
This is supporting evidence, not the product pitch. PrismCAD separates planning from execution so a language model cannot write freely into AutoCAD.
Constrained operation catalog
Intent is routed to named operations such as MoveEntities and RotateEntities. The model does not emit arbitrary AutoCAD command strings.
Validation
Proposed steps must match supported operations, parameters, and the current drawing context before they are offered for approval.
Approval
The plugin shows the ordered plan. Only explicit user approval creates an execution authorization.
Context binding
The authorization is bound to the reviewed plan and relevant drawing context. If that context no longer matches, execution is refused.
Deterministic execution
The AutoCAD kernel runs the approved catalog operations. Multi-step failures abort without leaving earlier steps applied.
Local drawing handling
Planning runs on a local sidecar at 127.0.0.1. DWG and DXF bytes are not uploaded. Optional AI keys stay in local settings.
Auditability
Execution outcomes are stored in a hash-linked history with an execution ID. Later alteration of that history is detectable.
Licensing
A signed beta license identifies an authorized install and keeps a seven-day offline grace after successful validation.
Diagnostic consent
The free beta may upload a changed sanitized JSONL log at most once per UTC day. Read the privacy notice.

FAQ
Questions CAD teams actually ask
What can PrismCAD actually do?
The current beta can move, rotate, copy, and delete selected entities; update supported block attributes such as MATERIAL and MAT_CODE; insert supported fixtures (toilet, door at the cursor, wall, window); label named rooms/spaces; and extract existing room tags. Multi-step requests using then / and then / followed by / ; are shown as separate steps for approval. PrismCAD does not run arbitrary AutoCAD commands.
Does PrismCAD send my DWG to an AI provider?
No. DWG and DXF drawing bytes stay on the workstation. Supported basic requests are planned locally without an AI API key. If you optionally add an OpenAI-compatible key, prompt text and relevant retrieved context are sent to that provider—not the drawing file. The free beta separately may upload a sanitized diagnostic log at most once per UTC day when the log has changed.
Can PrismCAD make changes without my approval?
No. PrismCAD shows the proposed operation plan and waits for explicit approval before execution. Cancel makes no drawing change. A valid product license authorizes the installation; it does not approve an individual command plan.
Which AutoCAD versions are supported?
AutoCAD 2025 and AutoCAD 2026 on 64-bit Windows 10 or Windows 11. AutoCAD 2027 and later are not supported in this bundle.
Does PrismCAD generate arbitrary AutoCAD code?
No. Natural-language intent is mapped to a constrained catalog of named operations. Only those validated operations can change the drawing, and only after you approve the plan.
Can I undo PrismCAD operations?
If a multi-step plan fails during execution, PrismCAD aborts the transaction so earlier steps are not left applied. After a successful approved run, use AutoCAD’s standard UNDO command to reverse the drawing change.
Is PrismCAD free?
The current beta license is free after you accept the diagnostic-log agreement. No paid production tier is offered. The public Windows installer will open after publisher signing.
Does it work offline?
Planning runs on a local sidecar. Supported basic requests do not require an AI API key. License issuance and first validation need internet access; after a successful validation the plugin keeps a seven-day offline grace. Optional AI interpretation and diagnostic-log upload require internet access.
Spend less time repeating AutoCAD commands.
